Abstract
Objectives: Recent evidence indicates that rosuvastatin 40 mg may exert a beneficial effect in both carotid and coronary atherosclerosis progression. In particular, 2-year rosuvastatin treatment reduced the progression of carotid intima-media thickness (cIMT) in patients with low cardiovascular risk. However, despite the fact that in clinical practice lower doses of rosuvastatin are usually administered at this time, there are no clear data about its effect on cIMT. Thus, the aim of this study was to evaluate the effect of rosuvastatin 10 mg/day on cIMT over a 2-year follow-up.
Methods: Forty-five patients with hypercholesterolemia and asymptomatic carotid atherosclerosis on baseline carotid ultrasound investigation were treated with rosuvastatin 10 mg/day for 24 months. cIMT and lipid profile were assessed after 12 months and at the end of the study (24 months).
Results: After 24 months, the treatment showed a 35.67% reduction in low-density lipoprotein cholesterol concentration (171 vs 110 mg/dl; p < 0.001), a 32.27% reduction in total cholesterol (251 vs 170 mg/dl; p < 0.001), a 19.67% increase in high-density lipoprotein cholesterol concentration (49 vs 61 mg/dl; p < 0.001), and a 10% reduction in triglycerides (120 vs 108 mg/dl; p < 0.01). Rosuvastatin treatment was associated with a 26.6% reduction in left cIMT (1.20 vs 0.90 mm; p < 0.001) and a 22.2% reduction in right cIMT (1.22 vs 0.95 mm; p < 0.001).
Conclusion: Two-year treatment with rosuvastatin 10 mg/day in hypercholesterolemic adults with evidence of subclinical atherosclerosis establishes a significant reduction in cIMT and improves lipid and lipoprotein levels, with a good tolerability profile.
